Objective:
To explore the characteristics and diagnostic values of bone marrow cell morphology and immunophenotyping in lymphoma cell leukemia patients.
Methods:
Data of the bone marrow cell morphology and immunophenotyping of 35 patients with lymphoma cell leukemia admitted from January 2012 to January 2017 were analyzed retrospectively, and the value of bone marrow cell morphology and immunophenotype in the diagnosis of lymphoma cell leukemia was evaluated.
Results:
Bone marrow cell morphological examination showed the typical lymphoma cells in all the patients. The expression of differentiation antigens in lymphoma cell leukemia was consistent with that of original pathological diagnosis. In T-cell lymphoma cell leukemia, the expression of CD7, CD3, CD2, CD5, CD11b, CD34, and HLA-DR were present predominantly, among them the CD7 was the most sensitive antigen and its positive expression rate was 69.2%. In B-cell lymphoma cell leukemia, the expression of CD19, CD20, CD22, CD79a, Skappa, and early antigen HLA-DR were observed predominantly, among them the positive expression rate of CD19 was the highest (89.5%). Out of 35 cases, 28 cases showed that the percentage of lymphoma cells on bone marrow smears was consistent with that of bone marrow immunophenotyping, and 7 cases showed that the percentage of lymphoma cells between bone marrow smears and immunophenotyping differed by more than 1.5-fold.
Conclusion:
Bone marrow slides combined with immunophenotyping may be helpful for judging lymphoma cell marrow invasion and making early diagnosis of lymphoma cell leukemia.
